seriously, this may be my most hated thing people do ever. If i start reading an article and it contains the word 'yr' then i immediately pour petrol over it and set it on fire, then go round to their headquarters and shoot them all in the face at close range with a sawn off shotgun. PLEASE STOP IT IT MAKES ME HATE YOU

because it's part of the persona he's created about himself as a writer (that totally extends to just private emails and whatnot); using it as an affectation just to be more indie/punk/DIY is a bit suspect. I think the only time I ever used it was to make a joke about twee. But I think as far as Plan B = yr, that's by and large just kick, like.

that extends throughout all your work (or at least all your work under a given name); an affectation would be self-consciously borrowing the odd bit here, the odd bit there, chopping and changing to suit needs

...'persona' is the social component of the personality as defined by Jung. it's how you choose to present yrself (ha!) (although becomes habitual - "we become our masks" - wilde)

and if personality is ultimately only a collection of behavioural habits, a persona shd (yes!) be seen as a consistent collection of such integrated with each other and functionally stable.

...whereas an affectation wd (again!) be a single behaviour that either has no real root in the person beneath - ie repeated without knowing why - or just hasn't become a habitual part of its owner/host yet..?
